STRlKlNG MECHANISM...

SPEGIFIGATION forming part of Letters Patent No. 783,677, dated February 28, 1905.

Application filed January 30, 1904:. Serial No. 191.257.

To all whom it TI'I/(J/Z/ concern:

Be it known that I, AUeUs'rn ARTHUR CAILLE, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful liinprovements in Striking Mechanism, of which the following is a specification, reference being had therein to the aecompanying drawings.

This invention relates to improvements in striking-machines for testing the strength of a person in delivering a blow with the list; and its object is to provide a very strong, simple, cheap, and compact device for the purpose, provided with indicating mechanism and with adjusting means whereby the relation of the indicated to the real force of the blow may be changed.

A further object of the invention is to so construct the device that the shock of the blow will not be transmitted to the indicating means and to provide means for controlling the operation of said means by a coin.

It is also an object of the invention to provide certain other new and useful features, all as hereinafter more fully described, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a device embodying the invention; Fig. 2, an enlarged side elevation of the same with one side of the casing removed; Fig. 3, a central vertical section; Fig. 4, a section on the line w w of Fig. 2. Fig. 5 is a detail showing the indicating-hands and part of the operating mechanism therefor in perspective; Fig. 6, a detail showing the coin-chute in perspective, and Fig. 7 a detail perspective view of the forked lower end of the operating-arm for actuating the indicating mechanism.

A is a casing secured to the upper end of a standard or pedestal B.

C is a spring-casing extending from the rear side of the casing A, and D is a backing-board secured transversely to the end of the spring casing and adapted to be secured to a wall or other support to hold the device in place and take the force of the blows delivered upon the pad or buffer-head E at the opposite or 5 front side of the casing A.

F represents handles secured to the board I), one at each side of the machine, so that, if desired, the operator may test his strength by placing his chest against the buffer F. and, grasping the handles, force inward on said buffer.

(f is a suitable dial at the front of the casing above the buffer to indicate the force of the blow or the pressure applied to the buffer.

1 is a longitudinally-momble non-rotative shaft extending tranversely through the cas ing A into the longitudinal axis of the springeasing C and outward from the front side of the casing. To this forwardly-extending end of said shaft is secured the buffer E, and intermediate its ends the shaft is screw-threzuled and provided with an internallyscrew-threaded clamping-collar 2, made in halves bolted together to clamp the shaft, so that said collar will not turn thereon after it has been adjusted to any particular position. Abutting at one end against this collar is a tubular sleeve 3 on the shaft, and at its opposite end this sleeve engages a socket member i, loosely mounted on the shaft to receive one end of a heavy coiled spring 5, the opposite end of said spring engaging the board 1) to form the resistance to the longitudinal inward movement of the shaft. Secured in an opening in the shaft is a guidepin 6, which projects downwardly through a slot 7 in the bottom of the spring casing C to limit the movement of said shaft and prevent its rotation, and the sleeve 3 is slotted inward from one end at 8 to allow the pin to project through. The tension of the spring 5 may. thus be adjusted by turning the collar 2, as the sleeve 3 will be moved longi' tudinally on the shaft by said collar and move the socket member 4 thereon to further compress or let out on the spring. The sleeve is provided with graduation-marks on one side, and secured to the casing is a pointer 9 to indicate the amount of tension which has been put upon the spring, the graduations being marked to indicate the point where the sleeve must be set to put such a tension upon the spring that the number of pounds indicated by the dial Gr will correspond with the actual force of the blow. Extending through a transverse opening in the shaft is a verticallyextending operating-pin 10, adjustably held therein by a set-screw, and on the shaft between said pin and the end of the bearing for the shaft in the forward side of the casing is a collar 11, secured to the shaft to engage a washer 12, of leather or other suitable material, to take the force of the return movement of the shaft.

Secured to the forward edge of the casing is a coin-chute 13, communicating with an opening or slot 14 in said edge, and pivoted upon a stud 15, extending from the side of the casing, is the operatinglever 16, formed at its lower end with a beveled side 17 to engage the coin-chute near its lower end, said lever being normally held against the chute by a spring 18, attached at one end to the forward edge of the casing and at its opposite end to an ear on said lever. The lower end of the lever 16 is forked at 19, so that when there is no coin between it and the coin-chute, which is also forked at its lower end, the upper end of the operating-pin will pass through these forks and the lever will not be actuated by said pin; but when a coin is placed between and the shaft forced inward said pin 10 will engage the coin lying across the fork of said lever, and the lever will be swung on its pivot. To hold the operating-lever in the extreme position to which it is turned by the movement of the operating-pin, a curved brake-bar 20 is pivoted nearthe rear of the casing and is held in frictional contact with a lug 21 on the side of the lever by a coiled spring 22, attached to the opposite end of said bar, the opposite end of which spring is attached to the casing by an adjListing-turnbuckle 69, and to release said lever, so that it may be returned to its normal position by the spring 18, a bell-crank lever 23, pivoted at 24, is provided, having its short arm in engagement with a hook 25 -on the brake-bar and operated to force the brake downward against the action of the spring 22 by a push-pin 26, engaging the u pper end of its long arm and extending through the front of the casing above the coin-slot.

Mounted in bearings in the casing, with its forward end projecting a short distance through the axis of the dial G, is a small shaft or rod 27, to the extreme projecting end of which a hand or pointer 28 is secured, and on said shaft intermediate its ends is secured a bevel-gear 29, in mesh with a bevel-gear 30, mounted on a stud or stub-shaft 31, projecting inward from the side of the casing. A pinion 32 is also mounted on said stub-shaft 31 to turnthe gear 30, and to actuate said pinion a gear-segment 33, formed integral with the end of an arm 34, pivoted at its opposite end upon the stud 15, is provided. This segment is actuated by the operating-lever 16 by providing a spring connection between the two, said segment-arm 34 being provided with a downwardly and laterally extending arm 35 at the 48 until the arm engages its stop.

opposite side of its pivot, to which arm is attached one end of a coiled spring 36, the opposite end of said spring being attached to the operating-lever. The arm 35 is provided with a stop 37, with which the operating-lever is normally held in contact by the spring 36, and a set-screw 38 extends through said lever to engage the stop, so that the relative normal positions of said lever and segment may be adjusted. A second arm 39 on the segment extends in an opposite direction to the arm 35, and to its end is pivotally attached the pistonrod of an air-compression cylinder 40, which cylinder is pivotally attached at its upper end to a stud on the casing. hen a coin is insertedin the chute and a blow delivered upon the buffer-head, the operating-lever will be very suddenly sw ung on its pivot, and a sudden shock of this movement is prevented from being transmitted to the indicating-hands and means for operating the same by the spring connection between said operating-arm and segment, as said spring 36 will first yield without moving the segment, as shown in Fig. 3, and will thus gradually operate to turn the segment against the resistance of the air-compression cylinder.

While only one row of division-marks on the dial and one hand may be employed, it is preferable, to provide two rows and a hand for each row, as it will not be necessary in order to give the machine the proper range to make the division so small, and therefore a short hand 41 is provided. This short hand is secured to the end of a sleeve 42 on the shaft 27 and lies between the hand 28 and the dial-face, said sleeve being prevented from longitudinal movement on the shaft by the hand 28 engaging one end and a collar 43 at the opposite end.

Integral with the forward or right-hand edge of the hand 28 is a lip 44, extending inward toward the dial to engage and move the hand41, and secured to the sleeve 42 adjacent to the wall of the casing is an arm 45 to engage a stop 46 on said wall and limit the movement of the hands. A cable 47 issecured at one end to said sleeve and given several turns around the same in such a direction that a coiled spring 48, attached to its opposite end, will exert aforce to hold the arm 45 against its stop.

The parts are so arranged that when the rack is operated by the lever 16 the shaft 27 will be turned by the gearing and move the hand 28 to the right, the hand 41 being stationarily held by the spring 48 until the hand 28 makes one revolution and the lip 44 comes in contact with the hand 41, when said hand will be carried forward by the hand 28 against the action of said spring 48. The lever 16 being held by the brake 20 in the position to which it is turned, the hands are also held in the position to which they are turned thereby, and when the brake is released the hand 28 will be turned backward by the rack, the hand 41 being turned backward by the spring This retrograde movement of the hands is retarded, so that the force of the movement will be lessened, by securing one end of a cable 49 to the shaft, around which it is given several turns, and securing a coiled spring 50 to its opposite end, and the backward movement of the rack is retarded by the action of the cylinder 40.

If for any reason the shaft 1 should not be fully returned by its spring, so that the operating-pin is not passed through the forked ends past the face of the chute to engage the coin when the shaft is again forced inward, and a coin should be dropped in, so that the pin would engage it upon the return or outward movement of the shaft, the coin would receive the force of the spring and be bent or wedged into the lower end of the chute, thus causing trouble and perhaps breaking the parts. To provide for this contingency, the bottom of the chute is cut away at its lower end, and a movable member 51, which is slotted or forked at 52 to allow the operating-pin 10 to pass, is pivoted at 53 beneath the bottom of the chute and held by aspring 54 with its face 55 in line with said bottom. At the extreme lower end of the member 51, at one side of its fork, is a slight projection or lug 56, and at the opposite side of the fork is an ear 57, provided with a screw-threaded opening to receive a screw 58, adapted to be adjusted toward or from the lug to increase or diminish the distance between, according to the size of the coins to be used in operating the machine. The side portions 59 of the chute project slightly above its bottom at the lower end, and the forked lower end of the operating-lever 16 engages these sides when in its normal position or inoperative and forms the fourth side of the lower end of the chute. Therefore when a coin is inserted through the slot 14 it will pass down the chute and be supported. by the lug 56 and screw 58, across the forks of the movable member and operating-lever, and between their adjacent faces 55 and 17, respectively.

To prevent a coin from being put into the chute before the push-pin has been operated to release the operating-lever and return it to position against the chute, a sheet-metal strip 60, which extends across and forms the top of the chute, is pivoted to the sides of the chute at 61 and extends downward to near the lower end thereof, where it will be engaged by the, operating-lever when said lever moves into engagement with the chute and rock said strip on its pivot to move the upper end 62 from across the slot 14, said end being bent to project outward adjacent to said slot.

Secured to the side of the casing below the shaft 1 is a spring-operated bell 63 of the orwith the downwardly-projecting end of the operating-lever 10, so that when the shaft 1 is forced inward the lever 64f will be turned and the spring be wound. A pawl 65 engages a gear on the bell and holds the spring from opcrating to ring the bell, and a rod 66, provided with a coiled spring 67, sleeved thereon to hold the pawl in engagement with the gear, is attached at one end to the pawl and having its upper end bent at right angles to engage a laterally-extending pin 68 on the arm 39. When the segment 33 has moved a certain distance and the hands have been turned to a predetermined point, the pin 68 will engage the rod 66 and release the pawl, allowing the bell to ring.
